The top end surface of the suction tube 1 is exposed in the seawater above the surface of the sea bed, and the part below the top end surface of the suction tube 1 is buried in the sand below the surface of the sea bed.
As shown in fig. 1, at least a part of the column 2 is provided with a baffle hole 21, the baffle hole 21 is provided on the peripheral wall of the lower part of the column 2 and communicates the inner space and the outer space of the column 2, and the baffle hole 21 extends in a first direction, which is orthogonal to the longitudinal direction of the column 2, in other words, the first direction may be the radial direction of the column 2, or the first direction may be the horizontal direction.
When the tide rushes to the upright post 2 provided with the turbulence holes 21, the turbulence holes 21 penetrate through the peripheral wall of the upright post 2, so that the tide can enter the inside of the upright post 2 through the turbulence holes 21, the stop resistance of the upright post 2 to the tide is reduced, the buffer function is realized, and the formation of horseshoe-shaped vortex is inhibited.
